Chapter 4 - Parameter Description [FU1]

Related Functions: FU2-33 [Rated Motor Current]

FU1-54: Overload Warning Level

FU1-55: Overload Warning Time

The inverter generates an alarm signal when the output current has reached the FU1-54 [Overload Warning Level] for the FU1-55 [Overload Warning Time]. The alarm signal persists for the FU1-55 even if the current has become the level below the FU1-54.

Multi-function output terminal (MO-MG) is used as the alarm signal output. To output the alarm signal, set I/O 44 [Multifunction Output] to ‘OL’.

Note: Inverter is not tripped by this function.

Note: The set value is the percentage of FU2-33 [Rated Motor Current].
